CAP RETAINER.

Application filed March 18, 1921. Serial No. 453,467.

To all whom it may 00mm.-

Be it known that we, ARCHIBALD W. PAULL and JOHN A. MoGINNIs, bothcitizens of the United States, residing at Wheeling, in the county ofOhio and State of West Virginia,

have invented a new and useful Improvement in Cap Retainers, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification, inwhich Figure 1 is a side elevation of a collapsible tube having ourinvention applied thereto;

Figure 2 is a similar view showing the cap removed; and

Figure 3 is a plan view with the cap removed.

The invention relates to containers having removable caps, and moreparticularly to collapsible tubes and the like having screw caps whichare removed to permit of the discharge of the contents of the tube.

The object of our invention is to provide simple, convenient andinexpensive means .25 whereby the cap when removed remains attached tothe tube, so that it cannot become lost, the retaining device actingalso to hold the cap sufliciently away from the discharge orifice of thetube to prevent coming in contact with the material being discharged.

In the accompanying drawing, in which We have shown a preferredembodiment of our invention, the numeral 2 designates a portion of acollapsible tube of well known character, having the usual threaded neckportion 3 to receive the cap 4.

5 designates the retaining device and consists of a piece of flexiblewire having inherent elasticity. This wire is formed with a loop or eye6 at one end which is rotatably engaged with the cap below the shoulder7 thereof, and with a similar loop 8 at the other end which is rotatablyengaged with the neck portion 3 at the base of the screw the two eyes orloops as to increase its elasrial being discharged from the tube.

By the rotative engagement with both the cap and the tube, the cap maybe freely screwed on and unscrewed. It is, however, not necessary thatboth ends of the retainer shall be rotatively engaged and one endthereof may be made fast either to the cap or to the tube.

Our invention provides an extremely simple retaining device Which can beapplied to collapsible tubes and the like at comparati vely smallexpense and which has a sulficlent spring action to hold the cap awayfrom the mouth of the tube without the necessity of providing springcoils for this purpose.

We claim:

The combination with a container having a neck portion and a cap adaptedfor detachable engagement with said neck portion, of a retaining devicecomprising a single piece of resilient metal engaged at one end portionwith the cap and at the other end portion with said neck and adapted toautomatically lift said cap away from said neck upon disconnection ofthe detachable connection between said parts, said retaining devicehaving its intermediate portion flat, substantially as described.

In testimony whereof, we have hereunto set our hands.
